Answer:
There are 70 seats in the 20th row.
Step-by-step explanation:
This is because you add 2 seats every row. The 1st row has 32 seats and the second row has 34. Now, you have 18 more rows to go and each one increases by 2. In you do 18X2, you get 36. Do 34+36, you get 70.
Let me know if you need anything else. Have a nice day. :)
